NOTES: Entering Friday's game, the Thunder has not lost two straight home games since 2009, when the Thunder lost to the Portland Trail Blazers on Nov. 1 before losing an overtime game to the Los Angeles Lakers on Nov. 3. Oklahoma City is coming off a home loss to the Brooklyn Nets on Wednesday. "We've always had that bounce-back toughness that it takes in this league," Thunder head coach Scott Brooks said. "We don't like to lose one game, let alone two in a row." Oklahoma City has lost two games in a row once this season, when it lost on the road to the Minnesota Timberwolves on Dec. 20 and at the Miami Heat on Dec. 25. ... The last time the 76ers and Thunder played, Oklahoma City won a 116-109 overtime game in Philadelphia on Nov. 24. ... Collins said his team has to limit the free throw and fast break opportunities for the Thunder in order to have a chance. "The key thing is, can we keep them off the foul line?" Collins said. "Durant and Westbrook are, I think, three and four in fast break points in the league. So you can't give them those opportunities." In the Nov. 24 matchup, Oklahoma City shot 37 free throws, while Philadelphia only shot 17. The Thunder also led the 76ers in fast break points, 19-13.
